↓ Sixty statistics students are randomly selected. For each of them, the time of day they filled out the survey and num of family members is measured. a. For this sample of paired data, what does r represent, and what does p represent? b. Without doing any research or calculations, estimate the value of r. c. Does r change if time of day is converted to minutes rather than hours? A. r is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and p is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students. OB. r is a statistic that represents the proportion of the variation in number of family members that can be explained by variation in the time of day they filled out the survey, and p is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students. OC. r is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data, and p is a parameter that represents the proportion of the variation in number of family members that can be explained by variation in the time of day they filled out the survey. OD. r is a parameter that represents the value of the linear correlation coefficient that would be computed by using all of the paired data in the population of all statistics students, and p is a statistic that represents the value of the linear correlation coefficient computed from the paired sample data. b. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal rounded to one decimal place as needed.) A. The value of r is estimated to be because it is likely that there is no correlation between the number of family members and the time of day they filled out the survey.
